LATH ATTACHING DEVICE.

Specification of Letters Patent. Patented J 11y 11, 1911.

Application filed February 17, 1911. Serial No. 609,152.

its object is to provide a cheap effective devlce of this character which can be quickly,

and easily secured in operative position.

" In the accompanying drawing, Figure 1 is an elevation of a sheet of ribbed metal lath secured to a beam by means of these improved fastening devices. Fig. 2 is a perspective of -a small portion of ribbed metal lath, of a portion of a beam, and of a fastening device; Fig. 3 is aplan of a clip.' Fig. 4 is a plan of a modified form of clip. Fig. 5 shows another modification.

Similar reference characters refer to like parts throughout the several views.

Ribbed metal lath of thecharacter shown in Fig. 1 comprises a series of parallel ribs 1, formed by bending parallel imperfonte strips or bands of the sheet. metal, narrow strips 2 between the ribs, and tongues 3 connecting the adjacent strips and ribs. The clips 4 shown in Fig. 3 are sheared from sheet metal, preferably hard spring steel, and formed with teeth 5 and holes (3. When the metal lath is positioned, these slips may be driven onto the flanges 7 of the I beams 8, or onto other proper portions of structural members, the teeth 5 engaging the flanges so securely that the clip can be removed only by the use of considerable force. These clips extend along in the hollow ribs 1. The two thicknesses of these hollow ribs are perforated by'a proper tool and shortwires 9 are pushed through the holes and through holes 6 in the clips and bent over as shown in Fig. 2. The clips will be proportioned according to the size of the ribs and of the flanges onto which they are driven. They may be of any desired shape or material so longas they have engaging members and holes to receive retaining wires.

In Fig. 4 a modified form is shown Where the clip 10 has a single tooth 11,, the opposite sired.

edge 12 being straight, the holes 13 being the same as before described. After the metal lath has been secured to the beams, joists or uprights as described, plaster or cement may be applied to one or both sides in the usual manner. In Fig. 5 another modi. fi'ed form of clip is shown comprising a small plate :115 having the perforations 1G and the notch 17, into which notch the teeth 18 extend for the purpose of engaging the flange of the structural member. A finger 19 is formed on the clip. When these articles are to be putinto use, the clips are driven onto the flanges of the rolled beams, and the ribbed sheetmetal is laid against the beams with the sides'ot' the ribs extending down over the clips. A blow with a hammer will force the finger 19 through the sheet metal, whereupon the fi'ngers may be bent back against the ribs as shown in dotted lines in Fig. 5. The fastening wires 9 may be also employed 1f de- .Having now explained my construction, what I claim as my niveutlon and desire to secure by Letters Patent, is

A 1. A clip for-securing ribbed sheet metal in position on flanged structural members, comprising a fiat metal plate having a slot so said plate may be driven onto said flanges, said plate being formed with teeth projecting into said slot so as to engage the flange of the structural member in the slot, and an outwardly extending finger on one edge adapted to be bent down to hold the sheet metal against the structural member.

2. Afclip for securing ribbed sheet metal in position, comprising a flat perforated metal plate having a slot into which an engaging tooth extends, thereby reducing the width or opening of the. slot.

3. A clip for securing ribbed sheet metal in --.position, comprising a flat perforated metal plate having a slot into which an engaging tooth extends, thereby reducing the width or opening of the slot, and having a projecting finger adapted to be bent against the plate. I a

4-. A device for securing ribbed sheet meta i to the flanges of structural members coin prising a slotted and perforated plate adapted to be driven onto the flange of the structural materialso said flange extends;

into the slot, and to project into the groove specification in the presence of two subformeld by ribbing the sheet metal, said scribing Witnesses. plate iaving an inwardly projecting engaging member, and a Wire fastener extending THOMA'J HENRY KANE 5 through perforations in the rib and in the Witnesses;
